"Diaz was spitting out blood out of his mouth towards me," Spell wrote in the report, filed the day after the arrest of Diaz and Ricardo Perez. Diaz was kneeling and handcuffed when Spell approached the suspect, the report said.

"I told Diaz to stop spitting blood and to lay down prone, or I would force him down, which he refused to comply," Spell wrote in the report. "Not being in possession of latex gloves, I used my right foot forcefully onto the back side of Diaz's head, and forced him to the ground."

The incident reports details the accounts of all officers involved in the arrest of the two men, who were accused of leading police on a chase in a stolen a Toyota Camry from Hartford to West Hartford.

Perez led officers through several residential streets before the chase ended on Flatbush Avenue in West Hartford when officers deployed "speed sticks," according to Deputy Police Chief Brian Foley and a Hartford police report.

As officers approached the car after the chase, Perez hit a Hartford detective with the car, according to police, and hit four Hartford Police vehicles during the pursuit of the vehicle.

A dashcam mounted in a West Hartford Police cruiser appears to show Hartford officers kicking or stomping one of the suspects, who was in handcuffs, according to police.

Perez and Diaz had to be hospitalized and Hartford Police said they launched a preliminary investigation the next day when the suspects' bruised and cut faces appeared in mugshots and raised concerns in the department.

The report from Hartford Police said Perez violently struggled with officers and a West Hartford officer, Carlo Faienza, used a stun gun, but it did not affect the suspect, so an officer punched Perez in the torso.

Faienza wrote that Perez "appeared to be under the influence of something and was showing signs of enormous bursts of strength by keeping his hands underneath his body."
